I installed the springs on both of our LCPs after they had a few boxes of ammo through them. They ran 100% with the factory springs and have ran 100% with the #13s in them...this includes a few different brands of ball and a bunch of XTP sd loads. The only other mods I did to the gun "operational" wise were to polish their feed ramps and chambers with a felt dremel cone and some Flitz.
This vid should give you a good look at the grip...[video=youtube;p3FrOPrJ-q0]http://www.youtube.com/watch?v=p3FrOPrJ-q0[/video]
